WATER SYSTEM.

Application filed November 18, 1925. Serial No. 69,810.

This invention relates to water systems which comprise a pump, a storage tank in which water is stored under pressure, and

an air charger including a small tank in which air is trapped and forced into the storage tank during the operation of the pump for the purpose of compensating for the air which has been absorbed by the water in the tank. In systems of this type, a valve mechanism is employed either for connecting the charger tank with a drain and with a vent so that air may be received by the charger tank, or for connecting the charger tank between the pump and the storage tank and disconnecting the charger tank from a drain and a vent so that the air in the tank will be moved by water flowing from the pump into the storage tank.

One of the objects of the present invention is to simplify the construction of the valve mechanism for operating the air charger. This is accomplished in the present invention by providing a valve body having ports which are connected respectively with the pump, the storage tank, the bottom region of the charger tank, the upper region of the charger tank, a vent and a drain. A single valve member, having ports cooperating with the ports of the valve body, is movable into one position for connecting the pump and storage tank ports and for connecting the charger tank with the vent and drain; and is movable into another position for disconnecting the charger tank from the vent and the drain, and for connecting the charger tank in series between the pump and the storage tank.

A further object of the invention is to prevent the accumulation of rust and other foreign particles in the ports of the valve body. This is accomplished in the present invention by arranging the ports of the valve member and valve body so that, in either operating position of the valve, each port of the valve body will be connected with another port. In this way, any rust at the ports of the valve body will be scraped off by the valve member and will be removed therefrom by the passage of water through the valve member.

A further object of the invention is to provide an air-charger system in which relatively small passages are provided for conducting water into the auxiliary tank so that preferred form of the a relatively small valve member can be used, and at the same time to prevent the occurrence of abnormal pressures in the pumping system. In order to accomplish this object, the invention provides three ducts which are connected in parallel and altogether in series between the pump and the storage tank. One of these duct-s includes the charger tank into which water from the pump. is carried through a relatively small passage including a passage through the valve member and portion of the valve body. Another duct includes relatively small passages through the valve member and valve body which are connected while the charger tank is being drained. The other duct bypasses the valve mechanism and the two ducts referred to, and is provided with a restriction for diverting some of the water flowing from the pump to either of the ducts of relatively small-flow capacity, yet, providing for the flow of water from the pump to the tank to the extent that abnormal pressures in the pumping system will be prevented. This restriction is preferably provided by a port and a valve held against the port by a spring resisting the flow of water from the pump. The tension of the spring is adjusted so that water will be diverted to the other ducts in the manner referred to, while some of the water will pass through the port to relieve the pressure in the system.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a clearly shown.

In Fig. 1, 2O designates a pump-driving mechanism by which the rotation of a motor 21 causes the reciprocation of a pump rod 22 located within a well casing 23. The rod '7 22 operates the pumping members 24 and 25, which arelocated within pump cylinders 26 and 27, respectively. \Vater from the pump is discharged through a pipe 28 which is connected with an air-charger valve body 29, which is connected in a manner to be described, with apipe 30'leading to a pressure storage tank 31. Pipe 32 connects a drain pipe of the valve body 29 with the well casing.

Referring particularly to Figs. 4, 5 and 6, the valve body 29 is provided with three tubular recesses which are in alignment and which, together, constitute a passage through the valve body. One of these recesses is not numbered, but is provided by the tapered bore through the valve body 29 which provides a seat for the valve member 33. The other recesses are indicated by numerals 34 and 35, and are separated by a wall 36 having a threaded opening which receives a valve seat member 37 having ports 38 therein and closed by a spring-pressed valve 39 which is located in the recess 35. The valve member 33 provides walls for closing the ends of the recess which receives the valve member, and thus, separates the recess 34 from the ports through the valve member. The valve member 33 is maintained yieldingly upon its seat by spring 40 which is located within a recess 41 in the valve member and presses against a disc 42 provided with a point 43 received by a recess provided with a spring-retaining bracket 44 which is attached by screws 45 to the valve body 29. The valve member 33 is operated by a lever 46 connected therewith. The exterior wall of the recess 35 is provided with a threaded opening for receiving a plug 47 which is removable for providing access to the valve 39. By locating these recesses in alignment, the forming of the valve body by a casting process is facilitated and also the machining of the tapered valve seat and the machining of the surfaces which receive the valve cage 37 and the plug 47.

The tubular wall of the recess which receives the valve member 33 is provided with ports 50, 51, 52, 53, 54 and 55. The valve member 33 is provided with three passages 56, 57 and 58 which in either operating position of the valve, as shown in Figs. 6 and 7, connect each one of the valve body ports with another port so that, if there should be an accumulation of rust or other foreign particles at these ports, it will be dislodged by the movement of the valve and the move,- ment of water through the ports of the valve.

The pump discharge pipe 28 is connected with a passage 60 in the valve body 29, which passage is connected with the port 50 and also with the recess 34. The port 51 is connected by a pipe 61 with the bottom region of the charger tank 62. The port 52 is connected by a pipe 63 in the valve body which is connected by a pipe 64 with the upper region of the tank 62. The ports 53 and 54 lead into a vented drain chamber 65 which is connected with the drain pipe 32, and by a pipe 66 and a valve cage member 67 with a valve seat member 68 having air ports 69. Check valve 70 cooperates with the valve seat 68 to check the flow of water from the passage 66. The port 55 is connected with the recess 35 and also with a tubular passage 71 which is connected with the pipe 30.

To fill the auxiliary tank 62 with air, the valve member 33 is moved in the position shown in Fig. 7, the corresponding position of the levers 46 being indicated by suitable marks on the bracket 44. In this position of the valve 33, any water within the tank 62 may pass through passage 61, port 51, passage 57, port 54, drain chamber 65 and drain pipe 32 to the well casing. Air will enter the tank 62 through the air port 69, parts 67 and 66, chamber 65, port 53, passage 58, port 52, passages 63 and 64. Meanwhile, water may pass from the 'pump to the storage tank through pipe 28, passage 60, port 50, passage '56, port 55, passage 71, pipe 30. lVater will also flow through a by-pass around the valve 33 through a duct which comprises the passage 60, recess 34, the restriction provided by valve ports 38 and the valve 39, recess 35 and passages 71 and 30.

To trap the air in the tank 62 and cause the same to be forced into the storage tank 31, the valve member 33 is moved into the position shown in Fig. 6. The restriction provided by the ports 38 and valve 39 will cause some of the water flowing into the passage 60 to be diverted through the port 50, passage 56, port 51, into the tank 62. This will force the air in the tank downwardly through the pipe 64 and passage 63, ports 52, 57 and 55, and thence into the storage tank 31 through passages 71 and 30.

As it is not necessary that all the water discharged by the pump be conducted into the auxiliary tank 62 for forcing the air trapped therein and in the storage tank, the by-pass duct which includes the recess 34 and valve ports 38 is provided for conducting the water in excess of that needed for operating the air-charging apparatus. In this way, the dimension of the ports through the valve body and valve member can be limited, thereby reducing the size of these parts and cost of manufacture. Obviously, the valve 39 will be automatically opened to a greater or lesser degree, depending on the pressure in the pumping system. The valve 39, therefore, operates to divert water into the air-charging apparatus and also to prevent abnormal pressures in the system. In case the valve member 33 should be moved to-a position intermediate its operating positions, thereby interrupting the flow of water from the port 50 to the port 55, all the Water discharged from the pump will flow through the ported valve seat 37, the valve 39 yielding to accommodate the full capacity of the pump.

The mounting of the valve body upon a suitable vertical support] is provided by brackets and 81, which include sleeves 82 and 83, respectively, which engage tubular parts 84 and 85, respectively, of the valve body 29. The tubular part 85 provides the passage 60 and the tubular part 84 provides the passages 61 and 63, and is threaded at its upper end for receiving a collar 86'attached to the bottom wall of the tank 62.
